钢坯加热时燃气高温腐蚀的防护是迫切的工艺课题研究之一。这一课题用防护涂层法解决最为简单。所研究的搪瓷类涂料主要适用于高合金钢及合金的冲压和热挤压。由于这种涂料价格高、配制和涂敷工艺复杂并使轧辊的摩擦系数与咬入能力降低,因而
Billet heating gas at high temperature corrosion protection is an urgent project one of the topics. This topic is best solved with a protective coating method. The enamel coating studied is mainly suitable for high alloy steel and alloy stamping and hot extrusion. Due to the high cost of such coatings, complex formulation and coating processes and reduced roll friction and biting tolerance
